Like numerals refer to like parts throng out the several views of the drawings'.

Inthe drawings, 15 is the frame consisting of side standards 16 and 1'( suitably connected together' by a cross-head .18,5` The main driving shaft 19 is journaled to'rotate in bearings formed in brackets fast to the frame of the machine and to =lthe cross-head 18. Said driving shaft is rotated by means of a pulley 20 fast thereto, a loose pulley 9.1 also being provided and adapted to rotate upon the main driving shaft 19.

The lower needle cylinder is fast to a running ring 23 rotatably supported upon the bed-plate 24 which, in turn, is supported upon brackets 25 on the sidestandards 16 and 17. A gear ring 9.6 is fastened to the running ring 23 and is driven by a pinion 2? fast to a vertical shaft 28 journaled to rotate in suitable bearings 29 and 30 and rotated by .means of a bevel gear 3',fast to the lower end ot the shaft Z8 and meshing into a bevel gear fast to the main driving shaft 19.

The upper cylinder is fastened to a gear 34 which, in turn, is fastened to a run; ning ring 35, said ruiming ring being ronstructedto rotate in the upper bed-plate 36. Said upper bed-plate is adjustably fastened to brackets 37 which, in turn, are adjustalily supported upon and fastened to the side standards 16 and 17. The upper cylinder is rotated by means of the gear 3l which meshes into a pinion 38 fast to the vertical shaft 28.

The lower cylinder "22 is provided with a set of spring needles 39 and these are the primary needles. Said needles are adapted to slide in grooves 4() formed in the periphery of the primary cylinder 22. .llach of said needles has attached thereto a lark l1 and said needles and their jacks have a reciprocatoiy motion imparted thereto, in a manner well known to those skilled in the art, by the primary cams #l2 fast to brackets 43 which, in turn, 'are fastened to the bedplate Q4.

The upper or secondary set of needles il are mounted to slide in grooves 45 .in the periphery of the secondary cylinder 33. These'upper needles are provided with jacks 46 which engage. cams 4T fast to brackets 1S, 4f), and thus a reciprocatory motion is iniparted to the upper needles in a manner wtlll known to those skilled in this art. The priimary need-les are pressed to cast oil their old loo'ps by a stationary presser 58 and the secondary needles are pressed; to cast olf their loops by a rotary presserl 59, all in 5a manner well known to those skilled in this art.

TheY sinkers 50 and 51 are illustrated in 'detail in Figs. 12 and :13,.resvpectively- These sinlrers are mounted upon `a sinker carrier or wheel 52 which is fastened to and is ro tatable with a gear 53, said gear being-'io tatably mounted upon: a stud l54 fast to a bracket 55 which, in turn, is adjustably fastened to a bracket 56 by means of a set screw 57,Y the bracket 56 being fastened to the bed-plate 24.- The lgear 53 has a rotary motion imparted thereto by the needles El!) into which the teeth of said gear mesh. The detailed Construction of this sinker wheel and the general manner of its operation is fully illustrated in ll. S. patent issued to me August 27, 1907, No. 864,354. lll/hen thel sinker wheel is rotated byl the gear a reciprocatory motion is imparted to the silikers 5() and 51 by the non-rotary cam 52 fast to the .stud 54, whereby the saine are moved in and out between the primary needles 39 in a, manner well knmvn to those skilled in the rt and thee-yarn is thus tedn to the primary needles which take said yarn and feed, 1t to the secondary needles in the usual manner. The particular construction, howerer, and arrangement'of the sinkers 50 and 51. whereby the loose end of a jarn is carried by the sinkers 51 into the path of the other sinke-rs and in between the needles eonstitutes one of theA novel features of my invention in` combination with the yarn guides and the particular manner in which these sinkers. eoperate with the yarn guides to feed :i loose end of the varn to the primary needles will be more full,v described hereinafter. In this embodiment of my invention there are two yarn guides G() and ($1 (see Figs. il, (i and 7). The yarn guide (S0 eonsistsof a thin strip of metal fastened by a serew 62 to a hub O3. Said yarn guide is fastened as a whole to a rook-shaft' (i4 adapted to rock in suitable bearings in a braeliet (i5 which is` in turn, fastened to the bedplate 2l. 'lo'the opposite end of the rock shaft 6l is fastened a rorker-arin (i6 and this rocker arm Connected by a link (1T to an arm GS fast to a rock-shaft (3!) journaled in the bracket ($5 and having fastened at. its opposite end another arni T() whirh bears against a (fam T1.

The cani T1 is formed of a colla r 72 ha ving two (fain plates Til .and 7l fastened thereto. Said collar 72 is fastened by a serew 7? to anothenmm 76 which consists of a hub TT provided with a tiange 78 to which are at taehed two cam plates 79 and. 80. The rams T6 and 'T1 are thus fastened together and rotatable as one piece upon' a stud Si whieii is fastened to the bracket Said cams are prevented from rotating too freely upon the Stud Sl by means of a frietion washer and :l screw 855 projecting through said washer and having screw-threaded engagement with/one. end of the stud 81. The yarn guide. G1 also consists of a fiat piere of metal fastened to :1 hub 84 by a screw (Fig. 'and said yarn `guide is fastened y yto a rock-shaft 86 journaled in suitable bearings in the bracket U5, said roelrshaft having fastened to its opposite end a. rorkeiearm $7 to which is attached a link 88, the lower end of said link (Fig. 9) being fastened to an arm 8S) whieb, in turn` fastened to a roel(- shaft il() journaled to rock in bearings prov vided in the bracket 65. and to the other end of the shaft 90, adjacent to the primary cylinder 22, is fastened; an Varm 91, the free. end of which is adapted to bear against the ram 76 Figs 3 and 9)',

, 1t will be seen that if a rotary motion is imparted to the yarn guide cams 71 and 7U, a rocking motion will be imparted to the. arms 'and 91, to the rock-shafts 69 and 90 and to the arms G3 and 89 respectively. Thus, through the links G7 and 88 a roeleing motion will be imparted to the arms Q6 and 87 respectively, and to their roeklyarn 'guides no* and ($1.

The rock-shaft 119 has fastened thereto another rocker arm 121 (Figs. 1, f1 and 10) which is connected by a link to a rocker arni 128 pivoted at 121 to the side traine of the machine, said r-1 ckerarin he ing connected by a link 125 to a slide 12o.

The slide 126 is guided in ways 12T on top of a bracket 128 which is fastened to the cross-head 1S. A spring 129 holds the slide 12V normally in engagement with a stop lll last to the bracket 128. To the top ot the slide 1213 are 'fastened two cam plates 131 and 132. said cam-plates forming together a complete cam which is adapted to be engaged by a pin 133 (Figs. 3 and 4l, said pin 132i being fastened to the slide 94 and pro jerting downwardly therefrom, so that as the lower cylinder rotates said pin will pass between the cam plates 131 and 132 and be moved by said cam plates accordingr to thc position in which the Cain plates are located relatively to said pin, and this location et the ram plates is determined by the pattern chain mechanism hereinbcfore described said. pattern chain having fastened thereto a pl e1- rality of cam blocks 134; and 135). These cam blocks are adapted to engage the ,tree end of the rocker arm 118 as the pattern chain is moved along beneath the same and thus a rocking motion will be imparted to said rocker arm 11S and by it to the rocker shaft 119, rocker arm 121 and throngrh the link 122 a rocking motion will be, imparted to the rocker arm 123 and a reciproeattrv motion imparted to the slide 126 by said rocker arm through the link12f1 so that ille ram slide 126, with the cam plates ll and 132 thereon and constituting a closed valu. will be moved to different positions at dill'eront distances from the center ot' thr needle, cylinders, and as the needle cylinders are rotated by the mechanism hereinbetore di scribed, the pin 133 will be positioned by the, cam plates 131 and 132, so that the slide Lll may bc positioned with the tooth 102 ol'i the springr 101 in the notch 98 or in the noti-h 99 or in the notch 100 and when the rocker arm 118 is in the position illustrated in Fig. 1th the. slide 91 will be in the position illus trated in Fig. 4. ll'hen, however, the cam lloclt 115i is brought beneath the free end ot the arm 11S, then the Cam plates 1?1 and will he moved out radially slightly and to sullicient extent so that the pin 133. engaging,l the cam faro of the plate 131, will move the slide $14 until the tooth 102 of the sp1-iner 101 enters the notch 99. It will be noted that the block 135 is higher than the cam block 134, so that when the block 135 cornes beneath the rocker arm 118 said rocker arm will be tipped to a still greater extent than when cam block '1l-lll was in contact with the 'free end thereofY and for that reason the cam plates 131 and 132 will be moved :still farther from, the center of the needle cylluder and the pin 1543 again engaging; the tace of the can.: plato 12.1 will more thel slide Jl outward radially' until the stop tooth. 162 enters the notch 1an.

The usual operation of machines of this class is then followed' in knitting a yarn into a. fabric. the upper needles 44. coperatingf with the needles 39 and the: pressers 58 and 5ft together with the several needle rains` in the usual well known manner.A As the pattern chain moves along step by step it is .finally brought to the pdint where one of the cani blocks 181 engages the free end oi' the arni 118, lifting said arm suiiciently to rock the saine, together with the r0ckshaft '119 to which it 1s fastened, thus rocking' the arm 121 and, throuy h the link 122, rocker arni 123 and link moving; the slide '120 outwardly and' thus moving the cani plates 181 andv 13?J outwardly from the center o1" the needle cylinders, so that as the needle cylinders revolve in the direction of the arrow L. the pin 133 on the slide 94 will engage the cam 131 and said slide be moved outwardly, so that its outer end will assume the position (L (Fig. 4). As the cylinders continue to rotate, the slide 94 will then engage one of the arms on the rotary member 92 of the .leed A and rotate said rotary member ninety degrees, thus rotating the cams 71 and 7G ninety degrees and causing the arni. 7() to be rocked by the cam plate 73 outwardly from the carn 71. This will move the ariu 6R downwardly, piillinfbr downwardly upon the link 67, 1 cking the arm 66 and rock-shaft G4 to lraise he yarn guide 60.

The yarn guides "daring the diii'erent nim'enients of the mechanism hereinbe'lore described occupy four i'positions indicated positions d, c. f and o in Figs. 16 and 17. During' the operation of the machine, when one of the yarn Iguides is in operative posi-` irection'.4` of the y guides hereinbet'ore described orrore the yarn guido fieeupvingr the position f is earlied upwardly lo the position d. time: Carrying;- the varo between the Cnt read)Y to be ent.. lunnifdiatelj.' after arrivingr at the position a'. the yarn fuide will drop lo the position e and at this time the fevering ol' the yarn will takt place. While` th' operation is taking place with one ot the yarn guides. the other yarn guide will more from the position c to the poeition lr/ and thie rarries the tree end ot thi` varn down into the lg'oriition illuetrated in Fig. 1o. so that it will be engaged by the projection 17:3 on the sinker 5l and held down in the path ot the sinken; adjacent thereto. As soon as. the yarn has been engaged by said projection 17?) and carried into the path ot' the sinkers adjacent thereto, the yarn guide will rise. from the position 5'/ to the position t' and the yarn will then be taken by all ol the einkifrs 50 and and fed to the needlee` in the ueual manner. These dillerent positionsx ot the Uvarn guides are obtained by reason of the different throw@y of the yarn guide earn plates 73 and 7l, 79 and 80, said rain plates being formed, hereinbefore set forth, to tiret, raise the yarn guide to the poeition d and then drop it to the position e, the purpose of thiS .throw being to insure. tht` yarn. which is thrown out of operation being lifted out of the path ot the needles end the returning slight movement of the yarn guide to the position e iet for lthe purpose of giving the ryarn slack while it being eut by the cutters 151 and 152.

It will he understood that alter the yarn has been severed the loose end thereof will fall approximatelj.7 into the punition illus4 trated in Fig. 11T, the tree end ot the yarn falling over the ends of the einliers. ll', when the yarn haer been severed as hereinbefore set forth, the free. end should fly 'upwardly instead of 'lfallingr downwardly, then said tree end would strike the yarn guard 171, as 'illustrated in dotted liner. (Fig. 1T).y which would keep said free end from being thrown over the yarn guide Gti or (El. as; the ease n'iight be, and Subhequently 'the tree end otf the yarn would drop down into the position illustrated in Figi. 17 and lie along the tops: ot' the sinkers.

lt will be understood that one` ot thel few lures ot' novelty of this invention is the tin` ger 173 eoiperatingr with the Ivarn guide from which the tree end oll` the. yarn leads to lay said freey end 'in the path of the sinkere and to 'thus cause. the same to le guided with precision and arruraey between the needles: of the primari' eylinder. llaeh time i that the yarn guide.A change position one Yarn is out olil by the respective ot eutters for the 'particular toed lo which it bo` longs. The operation ot' the euttin merlin.- nism has been hereinbeiore fully eeerib'ed.

lt will biunderstood that when one ot the vani blorks. ,my lill, has moved the cam plate 15111 and lll into position so that the Slide J4 is mmm; `,inwardly to engage the :irme $52; on the rol member fr.) and i'hanfle the position oil they varn guidi4` these rain plates. Il-roilgh the mechanism whirh ie; ai touted by the rams Tl and To. with .eaid ya rn guides, will remain as thneI pwitioned alter the bleek 131 has passed the arm 11S. by reason of the fact that, said arm 11S will drop onto the pattern ehain 103i and thus the rams 131 and 132 will be movled back lo their normal position by the spring 1129 ani the slide 94 will then be moved bark lo the. position illustrated in Fig. l so as not lo engage any ot' the rotar),Y members 92, and until it does engage said rotary member:` again the reepeelive yarn guides ot' eael. feed will remain in the position to whiih they were moved when the slide 94 was moved outwardly. as just desrribed. Thus the number of eirrumterential stripes and the width of said .stripes may be determined by the pattern ehain and the. particular yarns led to the stripe at each rotation ot' the Cylinders will be determi': Al by the, height of the cam blocks 134 or 135, tor the reason that the slide 94, as hereinlwlore deeeribed, will be set at ditl'erent distant-ea radially from the center ot the needle arlinders and will thus operate the rotatable members J2 ot the di'erent feeds or not aw eordinej to the distance to which Said slide is moved radially with relation to the needle cylinders.

in the position illustrated 'in Fig. l it will not engage either of the rotatable nien'ioere` in the feed ,A or the feed B. l/Vhen it is in (he position where the tooth 102 enters the notch 99, then the slide is in the position marked a (Fig. l) and said slide will engage the rotatable member 92 of the feed A, but will not engage the rotatable member 92 of the feed B, as Said rotatable member is lo cated a greater dietance from thee/enter ot the needle cylinders tha-n the rotatable meinber of the feed A, but when said slide 94 is advanced until the. tooth 1.02 enters the notch 10U, then said slide will be in the position marked Z1 (Fig. el) and will engage both the. rotatable member 92 of the feed A and the rotatable member 92 of the feed E and, therefore, the yarn guides, in both ot these feeds in the. latter case will be operated to change the feed of the yarn to the needles.

lt is evident that a variety of combinations may be obtained by the mechanism hereinhefore set forth: First, the yyarns from the. two yarn guides may he alternately fed to the needles, one yarn being feclto the needles by one yarn guide and then said yarn guide moved out' ot' operative yrelation to the needles, while the other yarn ,.@gude is F or example. when the slide Sil? brought into operative relation thereto, the. yarn being cui' olil Jfrom each of the yarn guides which is out of operation alternately. and iu thisl case the fabric would be knit as of one yarn and then of another.l as illustrated iu Figs. lt) and 2t), producing eircumt'ercntial stripes. Second, one of the yarns may be continually knitted into the fabric. as hereinla-fore described, by leaving one of the varn guides stationary and causing the other to be moved into and out of operative relation to the needles, as illustrated iu Fig, 31. producing a circularl fabric with portions thereof of a double. thickness and other portions of a. single thickness. Third, b v the use of different heights` of cam blocks the yarn guides may be operated for one feed to eliange and not for another. Fourth, either one of the yarn guides or both may be left in operative position 'tor any desired length of time or for any desired length of fabric being knitted by throwing out the instrumentalities connecting the pattern chain with the cam for operating the slide 9-l-that is, by throwing out ot' operation the arm 118 (Fig. 10). Fifth, oue ot' the yarn guides may be/(eft in operative position while the other yarn guide is thrown into and out ot' operative position alternately in the same course, thus producing a reinforced portion of the fabric illustrated in Fig. 21 or the, longitudinal stripes or reinforced fabric illustrated in Fig. 2Q, this fabric being obtained, as hereinbefore described. by the use of more than one slide movable with the primary cylinder and operating the yarn guide mechanisms.
